New Haven Connecticut is better than NYC
I'd rate them
Buffalo
New Haven
Detroit (Style)
Chicago (Deep Dish)
NYC
The rest
Having lived in the Boston (MA) area and raising two kids here, I can tell you, without a doubt, the best pizza is whatever you grew up eating. We have an absolute abomination of a pizza parlor here called Amici's. The kids would go there after school and it was what everyone would have a kids birthdays. It is garbage, but it is my kids favorite. We tried hard with Buffalo pizza (La Nova, Bocce Club), but those come in second.
